3.3 Layout protection
3.3.1 Protecting the inverter and input power cable in short-circuit situations
Protect the inverter and input power cable in short circuit situations and against thermal overload. Arrange the protection according to the following guidelines.
Figure 3-14 Fuse configuration
Note: Select the fuse as the manual indicated. The fuse will protect the input power cable from damage in short-circuit situations. It will protect the surrounding devices when the internal of the inverter is short circuited.
3.3.2 Protecting the motor and motor cables
21
If the inverter is connected to multiple motors, a separate thermal overload switch or a circuit breaker must be used for protecting each cable and motor. These devices may require a separate fuse to cut off the short-circuit current. 3.3.3 Implementing a bypass connection
It is necessary to set power frequency and variable frequency conversion circuits for the assurance of continuous normal work of the inverter if faults occur in some significant situations.
In some special situations, for example, if it is only used in soft start, the inverter can be conversed into power frequency running after starting and some corresponding bypass should be added.
Never connect the supply power to the inverter output terminals U, V and W. Power line voltage applied to the output can result in permanent damage to the inverter.

P07.07 can select the parameter to be displayed or not by bit and 》/SHIFT can shift the parameters form left to right, QUICK/JOG (P07.02=2) can shift the parameters form right to left.
4.2.2 Displayed state of running parameters
After the inverter receives valid running commands, the inverter will enter into the running state and the keypad will display the running parameters. RUN/TUNE LED on the keypad is on, while the FWD/REV is determined by the current running direction which is shown as figure 4-2.
In the running state, there are 24 parameters can be selected to be displayed or not. They are: running frequency, set frequency, bus voltage, output voltage, output torque, PID given, PID feedback, input terminals state, output terminals state, torque set value, length value, PLC and the current stage of multi-step speeds, pulse counting value, AI1, AI2, AI3, HDI, percentage of motor overload, percentage of inverter overload, ramp given value, linear speed, AC input current. P07.05 and P07.06 can select the parameter to be displayed or not by bit and 》/SHIFT can shift the parameters form left to right, QUICK/JOG (P07.02=2) can shift the parameters from right to left.
4.2.3 Displayed state of fault
If the inverter detects the fault signal, it will enter into the fault pre-alarm displaying state. The keypad will display the fault code by flicking. The TRIP LED on the keypad is on, and the fault reset can be operated by the STOP/RST on the keypad, control terminals or communication commands.
4.2.4 Displayed state of function codes editing
In the state of stopping, running or fault, press PRG/ESC to enter into the editing state (if there is a password, see P07.00 ).The editing state is displayed on two classes of menu, and the order is: function code group/function code number→function code parameter, press DATA/ENT into the displayed state of function parameter. On this state, press DATA/ENT to save the parameters or press PRG/ESC to escape.

Remarks: Press both the PRG/ESC and the DATA/ENT can return to the second-level menu from the third-level menu. The difference is: pressing DATA/ENT will save the set parameters into the control panel, and then return to the second-level menu with shifting to the next function code automatically; while pressing PRG/ESC will directly return to the second-level menu without saving the parameters, and keep staying at the current function code.
Under the third-level menu, if the parameter has no flickering bit, it means the function code cannot be modified. The possible reasons could be:
1) This function code is not modifiable parameter, such as actual detected parameter, operation records and so on;
2) This function code is not modifiable in running state, but modifiable in stop state. Example: Set function code P00.01 from 0 to 1.

P00.14 Carrier frequency
setting
The relationship table of the motor type and carrier frequency:
Motor type Factory setting of carrier frequency
0.4~11kW 8kHz
15~110kW 4kHz
The advantage of high carrier frequency: ideal current waveform, little current harmonic wave and motor noise. The disadvantage of high carrier frequency: increasing the switch loss, increasing inverter temperature and the impact to the output capacity. The inverter needs to derate on high carrier frequency. At the same time, the leakage and electrical magnetic interference will increase. Applying low carrier frequency is contrary to the above, too low carrier frequency will cause unstable running, torque decreasing and surge.
The manufacturer has set a reasonable carrier frequency when the inverter is in factory. In general, users do not need to change the parameter.

These function codes define the V/F curve of Goodrive20 motor 1 to meet the need of different loads.
0:Straight line V/F curve；applying to the constant torque load
1: Multi-dots V/F curve 2: 1.3th power low torque V/F curve 3: 1.7th power low torque V/F curve 4: 2.0th power low torque V/F curve
Curves 2~4 apply to the torque loads such as fans and water pumps. Users can adjust according to the features of the loads to get the best performance.
5:Customized V/F(V/F separation); in this mode, V can be separated from f and f can be adjusted through the frequency given channel set by P00.06 or the voltage given channel set by P04.27 to change the feature of the curve. Note: Vb in the below picture is the motor rated voltage and

P04.01 Torque boost Torque boost to the output voltage for the features of low frequency torque. P04.01 is for the Max. output voltage Vb.
P04.02 defines the percentage of closing frequency of manual torque to fb.
Torque boost should be selected according to the load. The bigger the load is, the bigger the torque is. Too big torque boost is inappropriate because the motor will run with over magnetic, and the current of the inverter will increase to add the temperature of the inverter and decrease the efficiency. When the torque boost is set to 0.0%, the inverter is automatic torque boost.
Torque boost threshold: below this frequency point, the torque boost is valid, but over this frequency point, the torque boost is invalid.
